65 Cool Tool Hacks That are Super Useful for DIYers

Tool hacks usually happen on the fly, when you’re in a situation that calls for a tool to be modified slightly or used in a way that’s different than its intended purpose. Many of the following tool hacks were created for those reasons—and some were just stumbled upon while tinkering in the shop.

Quick Woodworking File

Quick Woodworking File

This woodworking file comes in handy for sanding in tight spaces. Cut a piece of sandpaper to fit around a paint stir stick. Then use spray adhesive or an all-purpose glue to adhere it to the stick. Write the sandpaper grit on the handle of the stir stick, if you plan to store it for later use.

Custom Pads for a Mechanic’s Vise

Custom Pads for a Mechanic’s Vise

Make custom pads for a mechanic’s vise by cutting wood blocks to fit across the vise shaft. Use a jigsaw to cut out the notches in the wood blocks, and add a bead of hot glue (optional) to hold them in place on the vise.

More Planing, Less Exercise

More Planing, Less Exercise

Planing boards with a portable planer can provide you with a lot of exercise. But rather than running from the infeed side to the outfeed side before the board flips your portable planer, try this instead: Attach your portable planer to a board; then fasten the board to a miter saw stand. Then planing boards won’t wear you out so quickly!

5 / 66
Paint Can Opener on Hand

Paint Can Opener on Hand

Always have a paint can opener on hand when you’re ready to start a painting project. Use pliers or a multitool to slightly bend open the loop of the opener. Then hook it onto the handle of the paint can you just purchased.

Use a Sneaker to Clean Sandpaper

Use a Sneaker to Clean Sandpaper

Make sandpaper nearly new again with a lowly old sneaker. Start up your power sander and dust collection system (remember to wear hearing and eye protection). Then slowly press the rubber sole of an old sneaker along the sandpaper—you'll see a difference instantly!

Two Sizes of Brad Nails in One Gun

Two Sizes of Brad Nails in One Gun

For small projects such as trimming one door, store two sizes of brad nails in one nail gun. This puts both sizes of nails right in your hand; you just have to open up the magazine and put the correct-size nail at the top when you need it.

12 / 66
Caulk Gun Clamp

Caulk Gun Clamp

Did you know that you can use a caulk gun as a clamp? It’s perfect for gluing up small projects such as a cutting board. Just place a couple of pieces of scrap wood or cardboard at the ends of the caulk gun and then squeeze the trigger to apply pressure.

13 / 66
Hammer Cushion

Hammer Cushion

A rubber chair leg cap instantly converts a hammer into a rubber mallet. And if you want to drive a nail without denting the surrounding wood, cut a hole in the rubber cap. Pound until the rubber strikes wood, then finish driving the nail with a nail set. A 1-1/8-in. rubber cap fits tightly over most hammers and costs about $1 at home centers and hardware stores.

Check if a Square is Square

Check if a Square is Square

Follow these simple steps for ensuring that your square is square: Align the short side of the square with the factory edge of a piece of plywood. Draw a line along the edge of the long side of the square. Flip over the tool and align the base of the mark with the same edge of the long side of the square. Draw another line. If the marks do not align perfectly, the square is not square.

How to Fix a Square

How to Fix a Square

Before tossing your off-kilter square and spending money on a new one, try fixing it with this simple process. Use a center punch, a hammer and an anvil. If the sides of the square are too close together, punch the inner corner. If the sides are too far apart, punch the outer corner. Check your progress, and repeat as needed until the square is square.

16 / 66
Lighted Screwdriver Hack

Lighted Screwdriver Hack

No need for fancy hand tools with built-in LED lights, opt for this lighted screwdriver hack instead. When working in a dark space such as inside a cabinet, make your own lighted screwdriver by taping a keychain-size flashlight to the shaft. It'll shine the light right where you need it.

17 / 66
Compressor Creeper

Compressor Creeper

Save your back by storing your air compressor on a mechanic’s creeper, so you can easily tote it around your workshop or garage. Depending on the size of your compressor, you may be able to store your hose on the creeper, too.

18 / 66
Saddles for Sawhorses

Saddles for Sawhorses

Give your sawhorses padded, non-marring surfaces that protect your projects by wrapping the top rails with pieces of old carpet or rugs. Use a utility knife and a straightedge to cut the carpet along the woven backing; then secure the pieces to the sawhorses with staples.

19 / 66
Bobby Pin Nail Holder

Bobby Pin Nail Holder

There's no need to risk hammering a finger when working with tiny nails or in tight quarters. A common bobby pin makes a great nail holder—and keeps your fingers at a safe distance! Once the nail is started, remove the bobby pin and continue hammering away.

Vise-Grips to Pull Nails

Vise-Grips to Pull Nails

Vise-Grip pliers make great nail pullers. The tool locks onto the nail, creating a secure hold, and the curve of the head provides excellent leverage. Use a putty knife under the pliers if you plan to salvage the material after removing the nails.

22 / 66
Circle Gets the Square

Circle Gets the Square

Here's a magical way to trace arcs and circles for project parts. Tap two finish nails at the ends of a desired diameter, then rotate a framing square against the nails while holding a pencil in the square's corner. Spray the underside of the square with silicone or rub on some paraffin so it'll glide smoother. Then practice a little to get the feel of the three-point contact technique. Square not square? We'll show you how to fix it.

23 / 66
Customized Chuck KeyFamily Handyman

Customized Chuck Key

If you've ever scraped your fingers when tightening a drill chuck, you'll love this tip. First measure the diameter and length of the chuck key's handle and drill a matching hole in the end of a 4-in. x 3/4-in.-diameter wood dowel. Then hold the handle in a vise and tap the dowel onto the chuck with a hammer. The advantages? Besides no longer scraping your fingers on the gears, you'll have increased leverage with less effort and a much more comfortable grip when tightening the chuck. Plus: Never lose your chuck key again!

24 / 66
Flush-Cutting HacksawFamily Handyman

Flush-Cutting Hacksaw

Trim dowel plugs flush on fine furniture projects without scarring the adjacent surface. Apply a couple of layers of masking tape or a single layer of duct tape to a hacksaw blade with an untaped section between for sawing. While you're sawing, the tape elevates the blade a smidgen so it can't scratch the surrounding wood. After sawing, lightly sand the dowel to even it with the wood. These are our 100 handiest shop tips.

With a thin-blade saw, saw a narrow kerf 1/4 in. into the end of a wood shim ($2 per pack at a home center). Press a finish nail into the slot, hold the shim against the molding and then drive in the nail. The soft wood shim lets you deliver a final firm blow to leave the nailhead nearly flush with the surface. Next, set the nail just below the surface with a nail set and apply wood filler.

PVC Sanding FilesFamily Handyman

PVC Sanding Files

Stick sandpaper to cutoff pieces of PVC water pipe with spray-on adhesive and you'll be able to sand concave curves to perfection. PVC pipe is labeled by inside diameter; here's an index for the outside diameter of useful pipe sizes.
  • 1/2-in. i.d. = 7/8-in. o.d.
  • 3/4-in. i.d. = 1-in. o.d.
  • 1-in. i.d. = 1-1/4-in. o.d.
  • 1-1/4-in. i.d. = 1-5/8-in. o.d.
  • 1-1/2-in. i.d. = 1-7/8-in. o.d.
To apply sandpaper to the pipe, spray both the paper and the pipe with a generous layer of adhesive. Let both surfaces dry several minutes before joining them. Use two grits on each pipe—80-grit for sculpting a precise radius, and 100- or 120-grit for finish sanding. When the sandpaper's worn out, just pull it off, spray fresh adhesive on a new strip and go back to having fun. Check out these other genius sanding tips.

Hang your roofing toolsFamily Handyman

Hang Your Roofing Tools

Use spring clamps to keep your hoses, extension cords, and other tools and materials from sliding off the roof. Don’t try this on brittle or scorching hot shingles or you may damage them. You can create a handier hook by sticking the clamp in a vise and bending up one of the handles.

34 / 66
Clamp with a tie-down strapFamily Handyman

Clamp With a Tie-Down Strap

If you need to clamp boxes together, a ratchet tie-down strap can often do the job just as well as band clamps. Just make sure to protect the wood under the ratchet and hooks with cardboard.

35 / 66
Mix Concrete with a RakeFamily Handyman

Mix Concrete with a Rake

Try a garden rake instead of a hoe the next time you have to mix concrete. The rake won't splash as much water over the edge, and the tines do a good job of combining the water with the powder. With a hoe, you waste a lot of time just pushing powder around the tub. A medium mixing tub like the one shown costs $7 at home centers.

36 / 66
Make mini roller coversFamily Handyman

Make Mini Roller Covers

Next time you’re in the paint department, pick up a 3-in. roller frame, the type that takes the same diameter cover as a standard 9-in. roller. You can then cut any 9-in. roller cover into three 3-in. covers to fit it. A 3-in. roller is perfect for painting trim or small stuff like a mailbox, but not every store carries 3-in. covers. This little trick will also cut the cost of the 3-in. roller covers in half.

Mark the 9-in. roller covers 3 in. in from each end. Cut into equal pieces with a hacksaw, holding the cover steady with a bar clamp. Trim the rough edges of the nap with scissors.

Use a level to Extend your table saw fenceFamily Handyman

Use a Level to Extend Your Table Saw Fence

The only way to achieve a perfectly straight cut is to keep your material tight up against the table saw fence. But that’s hard to do when you’re cutting a large sheet of plywood on your own. Extending the fence with a 4-ft. level will make it easier to keep the plywood on a straight and narrow path as it approaches and passes through the blade. Hold the level in place with a couple clamps.

Need a hole in hard soil? Use a Drill!

Have you ever waited too long to install your reflective driveway markers and discovered the ground was frozen? Or tried to install a yard sale sign in dry soil that's as hard as concrete? Well, why not treat it as if it really were concrete and drill holes into it with a masonry bit? This 3/8-in. x 12-in. bit costs less than $15 at home centers.

39 / 66
Make a blade for cutting foamFamily Handyman

Make a Blade for Cutting Foam

A jigsaw will cut through rigid foam like butter—except butter doesn’t crumble into thousands of bits that mess up your shop, basement or garage. If you remove the teeth from a jigsaw blade, it will cut the foam just as well but without the mess. Remove the teeth with a grinder, and be sure to wear eye protection. Hold on to the blade with locking pliers, not your fingers!

Lift heavy stuff with a flat pry barFamily Handyman

Lift Heavy Stuff With a Flat Pry Bar

If you’ve ever had to remove a solid-core door, you know how heavy they can be. Lifting them up to reinstall hinge pins can be a challenge if you’re working alone, but a flat pry bar (aka “flat bar”) can give you just the leverage you need.
If your flat bar won’t raise the door high enough, install a small block of wood at the fulcrum point of the pry bar to increase the lifting distance. Hold the block in place with a small screw and washer. Make sure the screw doesn’t poke through. If it does, grind off the end so it won’t damage the floor. This same setup can be used to raise bottom drywall sheets off the floor for fastening.

Next time you're nailing, do it in style with this sturdy but stylish hammer holder. To make one, use a hacksaw or band saw to cut away one side of a 6-in.-long piece of 2" PVC pipe, leaving 2 in. at the bottom to drop the hammer into. To create belt slots, drill 1/4-in. holes in two lines and clean out the waste between the holes with a rattail file. That's it—drop in the hammer and enjoy its easy-to-reach location.

HH screwdriver hammer stuck nails

More Leverage

Shove a screw driver under the hammer head to protect delicate surfaces, like cedar decking or any other finished surface. For a straight pull, size the screwdriver so the pivot point is as close to the nail as possible. The screwdriver also gives the hammer claw better leverage, so you can often rock the hammer directly back on its head rather than sideways. But not always. Use this straight pull only on nails that come out fairly easily or that aren’t driven deeply. Otherwise you could break a wooden-handled hammer. Although you can yank a lot harder on hammers with a fiberglass or steel handle, you’ll find it’s a lot easier to use a sideways pull.

Hand tools are great, but they’re even better when you use them creatively for things they’re not designed to do. Check out these 16 genius hand tool hacks you need to know.

Free Finger Saver

I build a lot of small projects, including wren and bluebird houses, and I use lots of small nails—so small that at times I can’t grip them to start the nail. My solution: a plastic lid from a small peanut can. Just trim the lid back and drill a small hole near the end. Then cut a slit leading away from the hole so when you pull the lid back it releases from the nail. — Miles Stromback

Give Yourself a Little Give

When drilling a smooth surface, it can be difficult to get a hole started without “walking” the bit. Some materials are soft enough that you can use a nail set or punch to create a dimple to seat the bit. But other materials, such as glass, are a little more challenging.

For this simple hack, keep some painter’s tape and dense cardboard in your tool bag. Tape the cardboard over the area you want to drill, then use a carbide-tipped bit at low-speed to create a divot in the material. The cardboard will steady the bit, and once you have a starter hole you can discard the cardboard and proceed as usual.

For more detailed instructions, a great starting point is this Family Handyman article: How to Drill Into Glass.

drill depth starterFamily Handyman

A Simpler Depth Stop

Chances are you’ve seen the trick of using electrical tape to mark a drill bit when you want to stop a hole at a specific target depth. That’s a great tip, but if you’re drilling multiple holes that tape can get ragged pretty quick, and once that happens, it’s no longer an accurate depth stop. Instead, use a permanent marker to indicate the target depth and you’ll get much more use out of it before it wears down. Once you’ve finished your project, simply wipe the drill bit with some paint remover or Goo Gone, and the marker ink should come right off.

To make this hack more effective, you’ll want to choose a marker color that stands out against the drill bit. Ideally, you’d have a few markers in your tool bag, depending on what kind of twist drill bit you prefer to use.

Super-Long Bit Extender

Sometimes you need just a little extra reach on your drill bit. You can run down to the local hardware store to buy an extender, but those prepackaged solutions carry a hefty price tag.

This how-to from Family Handyman reader Jonthan Spicker shows how to get the same reach on a shoe-string budget.
